Help modelling silicone baby fork (lumpy surfaces, lose of details, adjusting measurements of pins)
You should keep it low-poly as long as you're not glad with the general shape, then give it a Subdivision Surface modifier, and only apply the modifier when everything's ok (but always keep a low-poly version).
I would stick to the shape from top view. Make sure that the edges follow the shape so that it will be easy to add edge loops further on:

Use the Proportional Editing option to curve the spoon (hide the part that you don't want to deform):

Then extrude up:

Move down the outer edges:

Then add a Subdivision Surface modifier, add edge loops or bevels to sharp some angles, etc...
